Rhymes with scuffle, a fight. First used by MC Ricky D (a.k.a. Slick Rick) of Doug E. Fresh and The Get Fresh Crew on the 1985 hit "La Di Da Di". Later covered by Snoop Dogg (then known as Snoop Doggy Dogg).

There was a ruffle-duffel, five minutes it lasted
The mirror said "You are, you conceited bastard."

The dramatic element used to indicate a dream sequence (flash-forward or flash-back).

Went to the bathroom to wash up,
I threw some soap on my face,
And put my hands upon a cup,
And said um:
Mirror mirror on the wall, who is the top dog of them all?,
There was a ruffle-duffel,
Five minutes had lasted,
The mirror said: YOU ARE YOU CONCEITED BASTARD!!
-Snoop Doggy Dog
